the dark-appearing capsular space that would contain the glomerular filtrate in a

functioning kidney.

FIGURE 18.10 | Kidney: Transmission Electron

Micrograph of Podocyte and Glomerular

Capillary

This transmission electron micrograph shows the association of a podocyte with
glomerular capillaries in the renal corpuscle of kidney. The nucleus (3) and

cytoplasm of the podocyte (11) are separated from the adjacent basement
membrane of the capillary (13). The larger primary process of the podocyte
(12) extends from the podocyte cytoplasm (11) to surround the wall of the
capillary. The smaller pedicles (2, 5) from the primary process of the podocyte
(12) are attached to the basement membrane of the capillary (13). Between the

individual pedicles (2, 5) are the filtration slits (1). Separating the podocyte (3,
11) from the capillaries and adjacent podocytes is the clear capsular space (4).
In the lumen of the capillary (6, 8) are the nucleus of an endothelial cell (10)
